Class ZZ is the most commonly used tolerance class for production go\/no-go gauging in shop-floor and inspection environments. Each gage in the set carries a minus tolerance of 0.0002 inches, making this set appropriate for verifying drilled, reamed, or bored holes to standard dimensional tolerances. Machinists, tool and die makers, and quality control inspectors use plug gage sets like this to confirm hole acceptance quickly and consistently without the setup time required by indicating instruments.\u003c\/p\u003e\n\u003cp\u003eThis set is suited for general metalworking, machining, and inspection applications in job shops, production facilities, and maintenance departments. The 0.251 to 0.500 inch range covers a broad band of common fractional and decimal hole sizes encountered in typical machining work. The 250-piece count provides full incremental coverage across that range, reducing the need to interpolate or substitute gages during inspection routines. The set is appropriate for both incoming inspection and in-process quality checks on machined components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass ZZ tolerance class for standard production go\/no-go gauging applications\u003c\/li\u003e\n  \u003cli\u003eDiameter range of 0.251 to 0.500 inches with 250-piece incremental coverage\u003c\/li\u003e\n  \u003cli\u003eMinus tolerance of 0.0002 inches per gage for consistent hole acceptance criteria\u003c\/li\u003e\n  \u003cli\u003e250-piece set reduces gage substitution and speeds inspection throughput\u003c\/li\u003e\n  \u003cli\u003eWeighs 22 pounds, suited for bench or toolroom storage\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose Class ZZ plug gage set for standard go\/no-go hole inspection across the 0.251 to 0.500 inch diameter range in machining and metalworking inspection environments.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlug gages are handled and used by machinists, quality technicians, and tool room personnel following standard metrology practices. Gages should be kept clean and lightly oiled when stored to prevent corrosion that can affect dimensional accuracy. Handle gages carefully to avoid dropping, which can alter the ground diameter and invalidate the tolerance class. Periodic calibration against a certified master is recommended to verify gage integrity over time.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Class\u003c\/strong\u003e: ZZ\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Type\u003c\/strong\u003e: Minus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: 0.0002 inches (0.0002 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Diameter\u003c\/strong\u003e: 0.251 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Diameter\u003c\/strong\u003e: 0.500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 250\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 22 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111600\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 616-81216\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691496472882,"sku":"616-81216","price":168.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8d53f874818e4c55776cbd9e577538c9.jpg?v=1788285934","url":"https:\/\/voomisupply.com\/products\/value-collection-616-81216-class-zz-plug-gage-set-250-pc","provider":"Voomi Supply","version":"1.0","type":"link"}
